Influence of Semi-Recumbent Position on Intra-Abdominal Pressure as Measured by Bladder Pressure

摘要: Background Intra-abdominal pressure (IAP) obtained by bladder measurement is used to detect impending abdominal compartment syndrome (ACS), but, while it recommended use a supine position, the literature describes IAP in varying positions. This study evaluated impact of body position at differing head-of-bed (HOB) elevations on when planned be as surrogate measurement. Materials and methods Forty-five trauma patients admitted surgical intensive care unit underwent measurements 0, 15, 30, 45° HOB 30° plus 15° reverse Trendelenburg tilt; these were performed counterbalanced fashion assessed built-in angle indicators bed rails each bed. Study participants connected an monitoring kit via their indwelling Foley catheter. Results A total 675 with 135 five (0°, 15°, 30°, 45°, +15° tilt). Statistically significant differences occurred between all elevations. significance also different BMI statuses. Conclusions Elevating significantly increases Bladder nonsupine positions may not provide valid interpretation for IAP, more so cases increased mass index.
